Configuration module

Abstract

A brake control valve arrangement includes an electro-pneumatic brake control valve block having a hold valve and a vent valve, a main regulator valve and an emergency and a tare pressure regulator. The valve block has an inlet for a brake supply pressure and an outlet for a brake cylinder, wherein an inlet and a vent pneumatic opening is provided for the hold valve and vent valve. The arrangement also includes a configuration module in pneumatic connection with the brake supply pressure and providing a pneumatic path to the inlet, and a pneumatic path to the vent valve from the brake cylinder, the arrangement also including at least one choke configured to control air flow in pneumatic paths to the inlet opening and vent opening.

 a configuration module in pneumatic connection with the hold value and providing a pneumatic path to the inlet of the brake pressure supply, and a pneumatic path to the vent valve from the brake cylinder, the arrangement further comprising at least one choke configured to control air flow in pneumatic paths to the inlet of the hold valve and to the vent valve. 
 
     
     
       2. The brake control valve arrangement of  claim 1 , wherein the choke or chokes are configured to control air flow from the brake supply pressure to the hold valve and to the vent valve and to control flow of the brake cylinder pressure to the vent valve. 
     
     
       3. The brake control valve arrangement of  claim 1 , wherein the configuration module further includes a height adjuster that configures at least one of the emergency and tare regulators. 
     
     
       4. The brake control valve arrangement of  claim 1 , wherein the outlet of the brake supply pressure on the pressure valve unit and the hold valve inlet are substantially co-planar. 
     
     
       5. The brake control valve arrangement  claim 4 , wherein the vent valve inlet is substantially co-planar with the brake supply pressure outlet and hold valve inlet. 
     
     
       6. The brake control valve arrangement of  claim 1 , wherein the pneumatic valve unit controls pressure into two brake cylinders by a pair of hold valves and vent valves. 
     
     
       7. The brake control valve arrangement of  claim 6 , wherein a link valve controls air flow between the respective hold and vent valve pairs. 
     
     
       8. The brake control valve arrangement of  claim 1 , wherein the choke or chokes are provided by a choke plate arranged between the pneumatic valve block and the configuration module. 
     
     
       9. The brake control valve of  claim 1 , wherein the choke or chokes are provided in the form of a screw in choke. 
     
     
       10. The brake control valve arrangement of  claim 2 , wherein the configuration module further includes a height adjuster that configures at least one of the emergency and tare regulators. 
     
     
       11. The brake control valve arrangement of  claim 10 , wherein the outlet of the brake supply pressure on the pressure valve unit and the hold valve inlet are substantially co-planar. 
     
     
       12. The brake control valve arrangement  claim 11 , wherein the vent valve inlet is substantially co-planar with the brake supply pressure outlet and hold valve inlet. 
     
     
       13. The brake control valve arrangement of  claim 2 , wherein the outlet of the brake supply pressure on the pressure valve unit and the hold valve inlet are substantially co-planar. 
     
     
       14. The brake control valve arrangement  claim 3 , wherein the vent valve inlet is substantially co-planar with the brake supply pressure outlet and hold valve inlet. 
     
     
       15. The brake control valve arrangement of  claim 1 , wherein the pneumatic valve unit controls pressure into two brake cylinders by a pair of hold valves and vent valves. 
     
     
       16. The brake control valve arrangement of  claim 15 , wherein a link valve controls air flow between the respective hold and vent valve pairs. 
     
     
       17. The brake control valve arrangement of  claim 2 , wherein the choke or chokes are provided by a choke plate arranged between the pneumatic valve block and the configuration module. 
     
     
       18. The brake control valve of  claim 2 , wherein the choke or chokes are provided in the form of a screw in choke.
